Six people have been hospitalized Thursday night after the rollercoaster at the Daytona Beach Boardwalk malfunctioned, according to the Volusia County Sheriff’s Office.

All of the patients, among them two who were ejected and fell roughly 20 feet to the ground in the accident, were alert as they were loaded onto ambulances and transported to Halifax Health Medical Center. A hospital spokeswoman would not comment on their conditions.

In all, ten people were rescued from the stalled roller coaster, with some cars left dangling after the amusement park ride derailed, fire officials said.

“Daytona Beach Firefighters did an amazing job tonight rescuing the ten very frightened passengers on the rollercoaster,” said Sasha Staton, a Daytona Beach Fire Department spokeswoman to the Daytona Beach News-Journal. “They were faced with dangerous conditions as they worked as fast as possible to successfully extricate everyone safely.”

The rollercoaster is called the Sand Blaster. It opened on the Boardwalk at the beginning of August 2013, after being purchased the previous year from a shuttered amusement park in Delaware.

It is 85 feet high and has more than a half-mile of track. The three coaster cars were on a line of track that was about 30 feet from the ground. The front car was hanging down from the track. Two remained strapped in the car for more than 30 minutes while firefighters worked to pull them out, Staton said.
